There is already a DazToUnreal plugin that is actively developed and works quite well.
Having said this, I woudn’t like to see Epic Games pouring resources into a “native” solution for something like Daz when they are actively working on MetaHumans, and honestly, although I like Daz and have used those characters in a couple of projects with the aforementioned plugin, MetaHumans is my only go-to now, they just look soooo much better.
The MetaHumans tech will only improve and the time Epic spends trying to develop DQS for Daz would take resources away from MetaHumans.
